JOURNAL BEARING oR'RaILwny c ans App1ication filed August a, 19s '"seaa1 m. 475,331" I 1 I l v for railway cars and particularly to a Wedge provided with tool engaging means for facili-,{

' tating the prying down of the front end of the wedge to permit its withdrawal from the journal box. In the specific forms shown in the drawings my invention contemplatesfimprovements in the journal bearing shown and described in my co-pending application Serial No. 286,086 filed-lune 18', 1928.

In the accompanying drawings, which iln lustrate' two forms of journal bearings made in accordance with my invention, Figurel is a longitudinal section; Figure 2 is an enlarged front elevation of the wedge; Flgj ure 3 is a section taken on the line 33' of Figure 2; Figure 4 ispartly a front elevation and partlya section taken on the line l,4 of Figure 1 {Figure 5 is a sectional view of a modified form of wedge taken onthe line 55 of Figure 6; Figure 6 is a-front elevation of the modified form of wedge; and Figure 7 is a view similar to Figure L butshowing the modified form of wedge.

Referring to Figures 1 to 4, 7 indicates a journal box of the usual type provided at" its forward end with a pair of lateral depending lugs 8 engaging with the upper part of the front face 9 of the wedge 10 to retain the wedge in position in the box. The wedge is of the type shown in my co-pending application above referred to, having'its upper lowerredge of the hole 17 in the forms shown face 11 longitudinally curved to permit rocka curved flange, providing a-pair'of lateral hand holds 14 for use inwithdrawing the wedge from the journalbox. The flange is separated from the bearing portion of the I under face of the wedge by a recess 15 and I claim as new and desire to secure by Letters" Patent of'the United States is: l

the front edge of the brass is held against forward movement by means of an upwardly projecting flange 16 on the rear end of said brass and contactingwith the rear end of the wedge. The lower face of the brass uponthe axle in the usual manner;

rests an opening 17 positioned directly below the corresponding flange8 As these openings I cannotbe forged in the wedge; I form them a 3 drillingthrough the' hand holds and; into the recess; 15 which is provided with exten-v sions; 1-8 tol permit clearance for the end "of the drill which would otherwise strike the walls offthe' recess =and be deflectedflaterallya V In Figuresfi, 6" and 7 I have shown a modified form in which the tool iengaging shoulder, instead of-lbeing provided, by'the lower ,edge of allele in each hand-hold, is provided by the upper. face of Ta lug 19 projecting for thecorresp'onding' flange 8l 1 U :In disassemblingthe b earing boxis ja'cked'up or otherwise raised toremove the weight ofthe car from the axle; When this is done the wedge usually adheres to the "box and is' raised with it so that its frontend remains in contact w-ithfianges 8. While the hand-holds as set forth-in myprior applica .tioniprovide's means for'drawing the wedge wardlyfrom; the :hand-holddirectlybelow the 561151151 (I i forwardly outof thejOurnaL-box, they do 7 not provide effective means for-lowering the I wedge out of engagement with thefflanges 8 when'it adheres firmly'to the box; In such caseapry bar is used, its lower forward edge resting on-the shoulder formed'bythe end of the bar even the most tightly adhering wedge is easily pried down outof engagement with the retaining flange 8 so that it may bev drawn out bymeans of thehand-holds.
